A CORPORATION OF NEW FOLDABLE TYPE-WRITING MACHINE.

7 '0 all whomit may concern:

Be it known that I, PHILIPPE on Chart nor, a citizen of the UnitedStates, and resident of Charlestown, county of Suffolk, and State oflviassachusetts, have invented certain new and useful Improvements inFoldable Type-Writing Machines, of which the following is aspecification.

()ne of the principal objects of this invention is to provide atypewritin machine with a keyboard adapted to be b0 ily folded upwardlyand inwardly and to fit within the, body part or case of the typcwritingmachine, the keyboard frame being adapted to form a part of theinclosing case.

Another object of the invention is to provide a foldable typewritingmachine in which the keyboard is adapted to fold upwardly and inwardlyinto the carrying case, the key actuated levers for operating the typebars being mounted upon a common pivot, which pivot also forms the hingefor the keyboard section of the case.

Another object of the invention is to r0- vide a foldable typewritingmachine in w ich the platen carriage is mounted upon a foldable sectionof the inelosing case the said section and the platen carriage beingarranged to fold upwardly and inwardly into the body part of the machineframe.

Another objectof the invention is to pro vide a foldable typewritingmachine having a foldahle keyboard section and a foldable platencarriage section, and to provide a type bar action and a platen shiftmeans, all of which remain peri'nanently and operatively connected,whereby the, several parts of the machine may be folded for the purposeof making the machine compact without disconnecting any of the operativeparts, whereby upon opening or extending the ma- -ehine to operativeposition the several key actions will we properly connected for use.

There are other important objects and advantages of the invention whichwill more fully hereinafter appear, all of them, however, resulting in atypewriting machine adapted to be folded into a compact package forconvenience of transportation and storage.

In the drawings, Figure 1 is a longitudinal vertical sectional view ofthe machine in its folded position, portions thereof being shown in sideelevation in order to simplify the drawing;

F ig. 8 a plan view of the machine in its extended or normal operativeposition.

The machine, when folded, is adapted to be contained within arectangular box composed of the base section a, the front section b, therear section 0 and c, and the top section (Z and d. The front section bis hinged to the forward edge of the base section a the part c of therear section is hinged to the upper edge of the part c of said rearsection, and the part d of the to section hinged to the upper edge ofthe part c of the rear section. The two parts of the top section arehinged to ether as shown in the drawings. The mat section is adapted tobe folded down into substantially the same horizontal plane as thebasesection, and to form a portion of the base of the ma chine when it isopen or extended and in operative position. The )art, 0 of the rearsection is adapted to be folded down into the plane of the base sectionand to form a part thereof when the machine is in operative position, asshown in Fig. 3 of the drawing. The parts 03 and d of the cover sectionare adapted to be folded to the rear of the machine as shown in Fig. 3.

For convenience of reference the parts will be described in their normaloperative position, as shown in Fig. 3. Mounted on the front section bof the machine frame or case is a box-like keyboard frame 1, the saidframe being hinged to the main casing 2 by means of a transverse wire orrod 3, said rod passing through the upper roar parts of the side wallsof the keyboard frame and into the forwa d parts of the side walls ofthe mainframe. The keyboard frame is formed with a bottom plate 4, afront plate 5, a top 6 and the inclosing side walls 7. The side edges ofthe section b of the frame are turned upwardly shown in Fig. 4, and saidupturned flanges are provided at their forward ends with in wardlyextending pins 9. The side walls 7 of the keyboard frame are formed withlongitudinal grooves 10 which extend throughout the length of thekeyboard frame so that the said front section has a loose slidingconnection with the keyboard frame. This sliding connection is nrovidcdin order that the frame section b and the keyboard frame may be foldedsimultaneously rearwardly and upwardly to the position shown in Fig. l,in Which'position the bottom plate t and the front plate 5 of saidkeyboard section form portions of the inclosing box or case.

Mounted in the top plate of the keyboard frame are the verticallyarranged key bars 11, each of which is provided with a. finger piece 12at. its upper end. Within the keyboard section each key bar is providedwith a yoke 13 and with a depending stem 14. Surrounding this stem andconfined between a collar 15 and a cup 16 on the bottom plate 4. is aspring 17. The type bar levers 18 are all pivoted upon the hinge rod 3and are of different lengths to enable them to be connected to the keybars of the seven-1 1 banks of keys. Each key bar extends through itsyoke 13 and is connected to said yoke by means of a pin-and-slotconnection, as shown clearly in the drawings. Each type bar lever isformed in two sections. each of which is pivoted upon the common pivotrod 3. the said lever sections being formed with shoulders 19 which abuttogether when the keyboard is in its extended operative position. in themanner of the ordinary rule or knuckle joint.

Pivoted in the forward part of the main portion of the machine frame,near the base section a, are the type bars 20. each of which is formedat its lower end with forwardly extending arm 21. The rear end of therear section 18 of each type bar lever is connected to the arm 21 of itsassociated type bar by means of the pin-and slot connection 22. It ismanifest that by depressing one of the key bars its connected type barlever will be swung on the pivot 3, the rear end of said lever movingupwardly and thereby swinging the type bar on its pivot. Each type barcarries a type head 23 and said head is provided with a plurality ofprinting characters, as shown. To return the type bars and type barlovers to their normal position a spring 24 is provided for each lever.This spring is coiled about the pivot rod 3, one end being anchored to arigid rod 25 While the other end is permanently secured to the rearmember 18 of to form flanges 8, as-

the type bar lever, as shown clearly at 26. It is manifest that thekeyboard section may be folded upwardly and rearwardly to the positionshown in Fig. 1, without disconnecting the two parts of the type barlevers and without in any way disarranging or modifying the positions ofthe springs which serve to return the partsof the key action to theirnormal at-rest position upon the completion of the printing movement.

The section 0 of the inclosing casing is provided with four upwardlyextending posts 27 near the four corners thereof. Each of these posts,on its inner face, is formed with a vertical dm'ctaiLgroovc 28.he'carriage bed 29 is provided at its ends with vertical dovetailtongues or ribs 30 which are adapted to fit .within the dovetail groovesin the posts 27. On the innermost posts 27, near the upper ends thereof,are formed outwardly extending pivots 31 which pass through the sidewalls of the inclosing case or box, said pivots forming the means forconnecting the section 1: of the case to the main body portion thereof.By means of this arrangement of pivots the platen carriage and thesection 0 of the in closing case may be folded upwardly and forwardly tothe position shown in Fig. 1. When the machine is in its open extendedposition the section 0 of the inclosing case abutssquarely against therear edge of the base section a, as SllOWll clearly in Fig. 3.

The carriage bed is formed with longitudinally extending grooves 32which are adapted to receive longitudinally extending guide ribs 33formed on the platen carriage 34.. The platen carriage may be of anysuitable form, and. as shown in the drawing, it is provided with theupwardly extending end frames 35 in which the platen 36 is journaled.The platen shaft is provided with the usual hand knobs 37. Mounted onthe carriage bed is a spring drum 38, the carriage driving cord 39 beingconnected to the carriage, as shown clearly in Fig. 5. The carriage isprovided with. a forwardly extending carriage rack 40 which is adaptedto be engaged by an cscapement pawl 41, the said pawl being operatedthrough the universal bar 42. This bar is mounted on the base section aand is extended up into the path of the type bars, the spring 43returming said universal bar to its normal position after each printingor spacing movement.

Ribbon spools 44 are suitably mounted in the main frame, and said spoolsare openated by means of pawls 45 carried by the universal bar. Mountedon the carriage is a suitable line-spacing lever 46 and paper-feed rolls47. The line-space lever-is provided with a pawl adaptedrto engage theteeth of a ratchet wheel 48 secured to the end of the platen. l 3 9Mounted in the forward part of the keyboard frame is a space key 49,said key being mounted upon key bars similar in construction to the typekey bars; and the space key lever 50 is pivoted upon the hinge rod 3.This space-key lever is formed with a rearwardly extending section 50which is also pivoted upon the hinge rod 3, the two parts of thespace-key lever being formed with shoulders similar to the shoulders 19on the type bar levers. The rear ends of the space-key levers arepivotally connected to a universal bar operating lever which is pivotedcoincident with the type bar pivots and is similar to a type bar, exceptthat it is not provided with a type head. Said universal bar operatinglever will be swung rearwardly and downwardly upon the depression of thespace key and will engage the universal bar 42 in precisely the samemanner as a type bar.

Mounted at each side of the keyboard are two shift keys 51 and 52 whichare connected to shift levers 53 and 54 in precisely the same mannerthat the key bars are connected to the type bar levers. The shift leversare composed of a front section 55 and a rear section 56, said sectionsbeing pivoted on the hinge rod 3 and provided with shoulders similar tothe shoulders 19 of the type bar levers. The rear section 56 is composedof two members 57 and 58 hinged together at 59 and provided withshoulders 60 which abut together to form a rule or knuckle joint. Thepart 58 of the shift lever is tubular, and sliding therein is arearwardly extending bar 61 whose rear end is connected to a link 62 bya knuckle joint 63, the rear end of link 62 being pivotally connected tothe carriage bed at 64. The shift levers 53 and 54 are of differentlengths in order to move the car riage bed vertically differentdistances for the usual case shift action. It is manifest that bydepressing either of the shift keys the carriage bed and the partscarried thereby will be elevated, the carriage bed sliding vertically onthe posts 27.

By constructing the shift levers as described, the carriage bed may befolded upwardly and rearwardly to the position shown in Fig. 1. withoutdisconnecting said levers from said bed. The rear section of the shiftlever is extensible to permit of the upward swinging movement of thecarriage bed, as shown clearly in Fig. 1.

Any suitable form of escapement means may be employed and saidescapement means may be operated by any desired form and arrangement ofuniversal bar. It is also manifest that the ribbon operating mechanismmay be varied and that any suitable form of line spacing means andpaper-feed rolls may be employed;
